“…In terms of areas farmed, barley is the fourth most significant crop in the world, after maize, wheat, and rice [ 6 ]. The water shortage greatly reduces its yield potential and yearly productivity compared to the other grains described above [ 7 ]. Numerous studies worldwide showed that water deficit induces many changes in barley.…”

“…The occurrence of biotic stresses in legume production systems has impacted negatively on production and has resulted in significant yield losses globally [11][12][13]. In many breeding programmes, the key objective is to develop crop varieties that are adaptable to an array of stressors in order to meet global food demands [14][15][16], thus addressing sustainable development goals 1 and 2 of the United Nations [17]. Legume programmes have been improving gradually over the years and have advanced from traditional methods of breeding to using genomic tools [18].…”

Legume crops such as common bean, pea, alfalfa, cowpea, peanut, soybean and others contribute significantly to the diet of both humans and animals. They are also important in the improvement of cropping systems that employ rotation and fix atmospheric nitrogen. Biotic stresses hinder the production of leguminous crops, significantly limiting their yield potential. There is a need to understand the molecular and biochemical mechanisms involved in the response of these crops to biotic stressors. Simultaneous expressions of a number of genes responsible for specific traits of interest in legumes under biotic stress conditions have been reported, often with the functions of the identified genes unknown. Metabolomics can, therefore, be a complementary tool to understand the pathways involved in biotic stress response in legumes. Reports on legume metabolomic studies in response to biotic stress have paved the way in understanding stress-signalling pathways. This review provides a progress update on metabolomic studies of legumes in response to different biotic stresses. Metabolome annotation and data analysis platforms are discussed together with future prospects. The integration of metabolomics with other “omics” tools in breeding programmes can aid greatly in ensuring food security through the production of stress tolerant cultivars.

“…Spike length also did not show a strong correlation with yield, suggesting that longer spikes may not necessarily result in higher yields under drought stress. However, the thousand grain weight was positively correlated with yield, suggesting that it is an important factor in determining yield under drought stress [34].…”

Drought stress is a major abiotic constraint that significantly affects crop productivity, including bread wheat (Triticum aestivum L.). The aim of the current study is to characterize different bread wheat genotypes and determine the key traits associated with drought stress adaptation. A total of 20 bread wheat genotypes were evaluated under normal and drought stress conditions. The genotypes were assessed for various physiological, phenological, and agronomic attributes. The data were analyzed using appropriate multivariate statistical methods to identify genotypes with superior drought tolerance. The results revealed significant variations in drought stress responses among the bread wheat genotypes. Several genotypes, such as BLUE SILVER, AAS 2002, NARC 11, BORLAUG-16, and NARC SUPER exhibited promising traits related to drought stress adaptation in terms of yield-related traits and growth maintenance under drought conditions. Principal component analysis accounted for 71.2% and 75.0% of the total variance in the datasets under drought and normal conditions, respectively. Furthermore, the hierarchical cluster analysis grouped most wheat genotypes together under normal conditions, while greater variability in response was observed under drought stress. These findings provide valuable insights into the selection of bread wheat genotypes with improved drought tolerance, aiding breeders in developing drought resilient cultivars for sustainable agriculture.
